Última Osmoregulatory responses to dietary protein and water intake in the granivorous Zonotrichia capensis (Passerine, Emberizidae) RChHN ALDEA,PATRICIA; SABAT,PABLO. We studied the osmoregulatory responses of the granivore Zonotrichia capensis, acclimated to high- and low-protein diets as well as two levels of water intake. We tested whether Z. capensis has the ability to modify the proportion of nitrogenous waste in the excreta when protein intake and water intake varies. After 21 days of acclimation, plasma osmolality was not significantly affected by dietary treatment; however, excreta osmolality was higher in the high-protein group compared to the low-protein group. Nitrogenous wastes in Z. capensis are excreted mainly in the form of uric acid. The proportion of kidney devoted to medullary tissue was 40 % higher in dehydrated birds than in hydrated birds. Excreta osmolality was higher in dehydrated birds, and in... Tipo: Journal article Palavras-chave: Granivory; Kidney; Nitrogenous waste; Osmoregulation; Passerines. Ano: 2007 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0716-078X2007000400006 The role of facultatively nectarivorous birds as pollinators of Anarthrophyllum desideratum in the Patagonian steppe: a geographical approach Ecología austral Paiaro,Valeria; Cocucci,Andrea A; Oliva,Gabriel E; Sérsic,Alicia N. The endemic shrub Anarthrophyllum desideratum appears to be the only ornithophilous plant offering nectar as reward in the extensive Patagonian steppe. The identity of its floral visitor assemblage and to what extent this species depends on bird pollination for sexual reproduction is yet unknown. A. desideratum's vast distribution includes climatic gradients, which may promote geographical shifts in its floral visitors. The aims of this study were to determine the species dependence on pollinators to set fruits, to identify its floral visitor assemblages, to document possible geographical and environmental variation of these assemblages across the species range and to assess their temporal constancy. We conducted different pollination treatments in several...

Passerines: Eurylaimidae – Eopsaltriidae (Peters’s sequence). Naturalis Dekker, R.W.R.J.. The type specimens present in the National Museum of Natural History, Leiden, are listed for the Passerine families Eurylaimidae up to and including the Eopsaltriidae (following the sequence in Peters’s Check-list of the Birds of the World).

Ano: 2006 URL: http://www.repository.naturalis.nl/record/209741 Water economy of three Cinclodes (Furnariidae) species inhabiting marine and freshwater ecosystems RChHN SABAT,PABLO; NESPOLO,ROBERTO F; BOZINOVIC,FRANCISCO. Birds living in desert environments have been the preferred models for the study of physiological adaptations to water scarcity. Passerine birds living in marine coastal habitats face similar problems, yet physiological adaptations to water conservation in such species have been poorly documented. We measured total evaporative water loss (TEWL) and rates of oxygen consumption (VO2) in three species of passerine birds dwelling in marine and fresh water habitats. Mass specific total evaporative water loss was significantly lower in the marine species, Cinclodes nigrofumosus, than in species inhabiting areas near freshwater sources. We found a positive relationship between TEWL and VO2. The ratio of TEWL to VO2 (relative evaporative water loss, RTEWL) showed...
